Need help with texture swizzle application on Windows


I have been testing an OpenGL driver and would like to understand if there are any applications or benchmarks that we can use to check the performance for texture swizzle feature.

Thanks in advance.

AFAIK there isn’t a utility that tests this API function directly. Regardless of whether you try writing one/have someone write one the performance impact is fairly negligible. It looks like it costs a little more than a byte swap if anything.
